2. Science
 Comes from the Latin "scientia“ means
KNOWLEDGE
 Knowledge attained through study or practice
 Reasoned investigation or study of natural
phenomena with the objective of discovering
new principles and knowledge of natural
phenomena.
 produces useful models of reality.
 Natural sciences, the study of the natural world
 Social sciences, the systematic study of human
behavior and society.

3. Technology
 Practical application of science to
commerce or industry
 includes the skill, technique and
knowledge of the manipulation of nature
for human purposes, using scientific results
and knowledge.
 Improvisation of a preexisting solution to
produce a function dependent solution.

4. Engineering
 Practical application of math and science.
 design, create and production of new tools,
machines and systems for practical human
means by exploiting technology.
 Divided into several disciplines and sub
disciplines
 Broadly divided into…
 Chemical Engineering
 Civil Engineering
 Mechanical Engineering
 Electrical Engineering

5. Sun & Earth
The Earth is
moving
around the
Sun.
The Earth is
the center of
the universe.
the Sun revolved
around the Earth
and the other
planets revolved
around the Sun.
Ptolemy
Tycho Brahe
Copernicus
The Earth
and the
other
planets orbit
the Sun.
Galilio

6. God Particle
 Higgs field - is a possibly quantum field supposed to
be responsible for giving elementary particles
their masses.
 Boson - a type of particle that allows multiple
identical particles to exist in the same place in the
same quantum state
 Church : God created the universe and all in it. God
gave everything it’s structure, purpose, live and yes it’s
mass.
 Higgs Boson - what are we made out of.
 The missing piece of the puzzle to understand the
world

7. Steam Engine
Is it the air?? The smoke?? The fog??? …. Oh!
It’s the Steam 
 A small step for 3 men, a giant leap for
mankind.
 Works on the Principle of Complete or Partial
Vacuum with a Condenser.
 First Practically used to pump Water From Coal
Mines.
 James Watt credited for the major
Developments.

8.  Diabetes is caused by the lack of insulin
production known as hyperglycemia.
 Insulin is a hormone which is produced
by the pancreas.
 In 1921 Fredetick ,G. Banting and
Charles H. Best discovered an "anti-
diabetic factor“ in the dog's pancreas.
 In 1922 the effective treatment of
diabetes is discovered in Toronto.
INSULIN

9. Wheel
At first humans realized that heavy
objects could be moved easier if
something round was placed under it
and the object rolled over it.
Then logs were placed under an
object to drag it easily. This was
the invention of sledge.
With time the sledges started to wear
grooves into the rollers and humans noticed
that the grooved rollers actually worked
better, carrying the object further.

10. Wheel Cont..
Then the rollers were changed into
wheels & the first wooden cart was
made.
Next, the fixed axle was invented,
where the axle does not turn but is
solidly connected to the cart frame.
After that different two wheelers,four
wheelers etc are developed.

11. Calculators
 In 1642 Blaise Pascal
(1623-1662) invented an
adding machine named
pascaline.
 Thirty years after Pascal,
Leibniz devises a
calculator which allows to
easily multiply and divide
 The first automation of
addition (subtraction) is
probably the work of
Wilhem Schickard in 1623
 The first easy to use
calculator(Arithmometer)
has been designed in
1820 by the French
Thomas de Colmar.

12. Relationship
Scientists seek to under
stand need new tools to help
the natural world, and often
discover the answers.
Engineers use scientific
discoveries to design
products and processes
that meets society needs.
Technologies (products and processes) are the result of
engineered designs. They are created by technicians to
solve societal needs and wants.
ENGINEERING
TECHNOLOGY
SCIENCE

13. Application
 As knowledge
Through the knowledge of Science, Technology and
Engineering, the world has produced
Scientists, Technologists and Engineers who contributed
maximum for the benefit of human beings, the society
and the world at large.
 As Social Activity
Application of Science, Technology and Engineering
has made mankind a civilized sociable person.
 As Professional Activity
To-day Science, technology and Engineering have
developed so much to absorb large number of people
for their main occupation and profession.

14. Gene
 Molecular unit of heredity of a
living organism
 Evolving with the science
of genetics
 Existence of genes was first
suggested by Gregor Mendel
 Provides the opportunity
to improve human and
animal health
 Alteration of certain
probabilistic aspects of
heredity is possible
Gene Technology

15. Genetic Engineering
 Also called genetic modification
 Used in research, biotechnology, and
medicine
 Medicine
 Human growth hormones
 Treating infertility
 Monoclonal antibodies
 Research
 Cloning
 Suspended Animation
 Tissue Regeneration
 Agriculture
 Nano robotics
